Two others, a 40-year-old Palmwoods woman and a 38-year-old Alexandra Headland man, were charged with accessory after the fact to murder. The man, who identified himself on Saturday to waiting media only as “Joe”, was understood to be an occupant of the unit where a tense siege involving Sikorsky took place over the weekend.

Sikorsky barricaded himself inside a Sunshine Coast apartment during a “highly complex and lengthy negotiation”, which lasted nearly 28 hours, until he surrendered to police around 6.30pm Saturday.

On Sunday morning, the South Eastern Regional Crime Co-ordinator, Acting Detective Superintendent Mark White, said detectives had been working around the clock on the case.

“Our thoughts are very much with Miss Beilby’s family as they come to terms with and mourn her death,” Acting Detective Superintendent White said.

“We would like to thank the public for their assistance and co-operation throughout the early stages of this investigation.”

Ms Beilby’s sister Deanna opened up about the family’s tragic loss in a public post on Facebook.

“With a broken heart shattered into more than a million pieces our family is utterly destroyed to inform you all that Larissa has been taken from us,” she wrote.

“Our beautiful girl has been reunited with our beloved wife and mother. Fly high our darling angel, until we see you again Rissy.”

Sikorsky had been the subject of a massive manhunt since Wednesday, sought for questioning over the death of a then-unidentified girl found in a barrel on the back of a ute.
